Anet A6 Z axis motor bracket with 30mm space for Plum Shaft Coupling

thingiverse

I purchased an Aluminium Flexible Plum Shaft Coupling to minimize the Z wobble effect. Unfortunately, the item I received was significantly larger in diameter than the original stock unit (original: 19mm, mine: 25mm). To make matters worse, there's only a 24mm gap available for the stock component. After adding an extra 5mm to my coupling design, the resulting space is now 30mm in diameter.
